Turbomachine (10), in particular for a fuel cell system (1). The turbomachine (10) comprises a compressor (11), a drive device (20) and a shaft (14). The compressor (11) has a rotor (15) arranged on the shaft (14), a compressor inlet (11a) and a compressor outlet (11b). A working fluid can be delivered from the compressor inlet (11a) to the compressor outlet (11b). A drive cooling path (92) for cooling the drive device (20) branches off at the compressor outlet (11b). Also proposed is a fuel cell system (1) with a turbomachine (10) according to the invention, a method for operating the turbomachine (10) and a method for operating the fuel cell system (1).
